OK so I just removed the stock sub out of my 02 gs300 to make room in the trunk for my sub box, now my question is are there any negative effects to leaving the large opening on the deck?

 

I would like to know this too.

 

I don't see how there would be a negative impact. When I put my box in, the factory space will be open and allow air to pass through as well as bass in the cabin.

 

If you would have left the speaker and put in subs you would have had ur negative effects. That is considering you are pushin enough air around in the trunk. Wouldnt take much. I would imagine that stock sub sitting there taking hits would sound like a kazoo once the cone starts pulling apart. Ur all clear for bass now.

 

I would Dynamat that whole rear deck, it will rattle if you dont.

 

^^^ yup im doing top and bottom of the rear deck myself. Might as well since its expossed

 

i have my stock sub removed and the only down fall is that there's a little bit more rattling now. i'm thinking about dynomatting my rear deck as well

 

no down side, just allows the bass to pass through

 

The only downside I have with the opening is I can smell the leftovers I put in the trunk after dinner.

 

yeah if anything it lets air pass through. but i would dynamat or even stuff some rags or something in between the panel and the metal in there or it will rattle like mine was

 

Thanks for the replys everyone will look into the dynomat

 

Don't look into dynamat. It's VERY overpriced. Go on ebay and buy some AudioTechnix 60mil deadener
